基于AARRR模型的电力微信公众号信息溯源方法研究

Research on Information Tracing Method of WeChat Official Account Based on AARRR Model

现有电力微信公众号信息溯源方法会受到关系网络尺寸的限制,在10 000数量级以上网络尺寸中存在信息源定位准确度小的问题,为此提出基于AARRR模型的电力微信公众号信息溯源方法研究。构建电力微信公众号关系网络,通过AARRR模型获取信息传播路径。基于节点紧密度选取可观测节点,降低关系网络数量级,并计算信息传播激活时刻向量,利用BFS算法计算信息传播时间近似矩阵向量,依据计算的信息传播激活时刻向量与信息传播时间近似矩阵向量建立信息溯源估计函数,估计信息源节点,实现了电力微信公众号信息的溯源。实验结果表明:与现有代表方法相比较,提出方法在10 000数量级以上网络尺寸中溯源成功率高、真实源节点平均排名比例小,信息源定位准确度高,适合大力推广使用。

The information tracing method of the existing WeChat official account is limited by the size of the network.The accuracy of information source location is small if the network size is 10000 orders of magnitude.Therefore,the information tracing method of the official account of WeChat is proposed based on the AARRR model.The official account network of WeChat electric power is built,and the information transmission path is obtained through the AARRR model.Based on the node tightness,observable nodes are selected to reduce the order of the relational network,and the information propagation activation time vectors are calculated.The approximate matrix vectors of information propagation time are calculated by using the BFS algorithm.The information tracing function is established based on the information propagation time vectors and the approximate matrix vectors of information propagation time,and the information source nodes are estimated,thus the official account of WeChat electric power realizes traceability of information.The experimental results show that compared with the existing representative methods,the proposed method has high traceability success rate,small average ranking proportion of real source nodes,high accuracy of information source positioning,and is suitable for vigorously promotion and use.
